Roblox

Intel Core i5-11400F paired with Intel Arc B370 in Roblox delivers a playable experience at 1080p and 1440p, but falls short at 4K. The data shows a clear ceiling at 3840x2160, where even the lowest settings cannot maintain a 60 FPS average. At 2560x1440, the system comfortably clears the threshold across all presets, with Ultra settings averaging 67 FPS. At 1920x1080, performance is strong, with Ultra settings averaging 101 FPS and Low settings reaching 154 FPS. The bottleneck shifts from the GPU at 4K to a more balanced load at lower resolutions, where the CPU's six cores and twelve threads provide ample headroom for Roblox's physics and scripting workloads.

Best Settings per Resolution

At 3840x2160, the recorded data indicates no preset achieves the 60 FPS playable threshold. The highest average FPS at this resolution is 58 on Low settings, which falls short. Medium settings average 53 FPS with a minimum of 45 and maximum of 61, showing occasional dips below playable territory. High settings average 47 FPS, and Ultra averages 38 FPS. The verdict is clear: 4K is not viable for smooth gameplay with this combination.

At 2560x1440, the system performs admirably. The most demanding preset, Ultra, maintains an average of 67 FPS, which stays above the 60 FPS threshold. This is the recommended setting for 1440p, as it delivers the best visual quality without sacrificing smoothness. Medium settings average 94 FPS, High averages 83 FPS, and Low averages 103 FPS. The minimum recorded FPS at Medium is 80, indicating consistent frame delivery even in demanding scenes.

At 1920x1080, the system has significant headroom. The best visual preset, Ultra, averages 101 FPS, which is well above the playable threshold. This is the optimal choice for 1080p, as it maximizes graphical fidelity while maintaining high frame rates. Medium settings average 140 FPS, High averages 124 FPS, and Low averages 154 FPS. The minimum FPS at Medium is 119, showing that even the lower bound remains comfortably above 60 FPS.

CPU and GPU Roles

The performance scaling across resolutions reveals how the workload shifts between the Intel Core i5-11400F and the Intel Arc B370. At 3840x2160, the GPU is the limiting factor. Dropping from High to Low settings at 4K only improves the average FPS from 47 to 58, a gain of 11 FPS. This modest improvement indicates that the Arc B370, with its 1280 shading units and 6.144 TFLOPS of FP32 performance, is saturated at this resolution regardless of preset. The GPU's percentile rank of 5 among all tested GPUs confirms its position as a low-end part.

At 2560x1440, the balance shifts. The difference between Low and Ultra settings is 36 FPS (103 vs 67), showing that the GPU still has significant influence. However, the CPU begins to matter more. The Core i5-11400F, with its 12 threads and Cinebench R23 multi-core score of 14340, can feed frames fast enough to keep the GPU busy. The 1440p results show a 24% performance drop from Low to Ultra, which is less severe than the 35% drop at 4K, indicating that the CPU is starting to share the load.

At 1920x1080, the CPU becomes the primary constraint for high frame rates. The gap between Low and Ultra settings narrows to 53 FPS (154 vs 101), a 34% reduction. At this resolution, the Arc B370 is less stressed, and the i5-11400F's single-thread performance (Geekbench single-core score of 1777) becomes more relevant. The 1080p Low setting at 154 FPS suggests that the CPU can push high frame rates, but the GPU limits the Ultra preset to 101 FPS. This is typical for Roblox, where CPU-bound scenarios like complex worlds with many players can reduce frame rates regardless of GPU capability.

Measured FPS Breakdown

At 1920x1080, the full range of settings shows a clear hierarchy. Low settings produce the highest average at 154 FPS. Medium settings reduce this to 140 FPS, with a minimum of 119 and maximum of 161. High settings average 124 FPS. Ultra settings average 101 FPS, which is the lowest at this resolution but still far above the playable threshold. The data shows a 53 FPS spread between Low and Ultra, indicating that the GPU has a measurable impact even at 1080p.

At 2560x1440, the same pattern holds with lower absolute numbers. Low settings average 103 FPS. Medium settings average 94 FPS, with a minimum of 80 and maximum of 108. High settings average 83 FPS. Ultra settings average 67 FPS, which is the only preset at this resolution that dips close to the 60 FPS threshold. The spread between Low and Ultra is 36 FPS, showing that the GPU has a larger relative impact at 1440p compared to 1080p.

At 3840x2160, the results are consistently below 60 FPS. Low settings average 58 FPS, which is the best result at this resolution. Medium settings average 53 FPS, with a minimum of 45 and maximum of 61. High settings average 47 FPS. Ultra settings average 38 FPS. The spread between Low and Ultra is 20 FPS, which is smaller than at lower resolutions. This indicates that the GPU is the dominant bottleneck at 4K, as changing settings has a limited effect on the final frame rate.

How This Combo Ranks

The combination of the Intel Core i5-11400F and Intel Arc B370 ranks 3417 out of 3711 tested combos for this game. This places it in the bottom 8% of all systems tested. The low ranking is primarily driven by the GPU, which has a percentile rank of 5 among all GPUs. The CPU, in contrast, has a percentile rank of 71, meaning it outperforms most processors in the database. The mismatch between the CPU's capability and the GPU's limitation explains why this combo struggles at higher resolutions.

The combo ranking reflects the fact that Roblox can be demanding at high settings and resolutions. While the i5-11400F is a capable mid-range CPU, the Arc B370 is positioned as an integrated-class graphics solution with a 25 W TDP. This pairing works well for 1080p and 1440p gaming, but it cannot handle 4K. The rank of 3417 out of 3711 suggests that users of this system should expect to play at lower resolutions or reduce graphics settings to maintain playable frame rates.

Similar Performance Alternatives

For the CPU, the nearest rivals in the database show that the Intel Core i5-11400F is closely matched by several other processors. The AMD EPYC 7H12 has an average score of 17120, which is 0.3% higher than the i5-11400F's average of 17177. The Intel Core i5-12450H scores 17239, a 0.4% difference. The AMD Ryzen 3 PRO 8300G scores 17278, a 0.6% difference. The Intel Core Ultra 7 164U scores 17074, a 0.6% difference. These CPUs would perform nearly identically in Roblox, as the game's CPU demands are modest and the single-thread performance differences are minimal.

For the GPU, the nearest rivals highlight the Arc B370's low-end positioning. The ATI Mobility Radeon HD 5570 has an average score of 1186, which is 0.2% higher than the Arc B370's 1184. The ATI Radeon HD 5770 scores 1190, a 0.5% difference. The AMD Radeon HD 7650M scores 1192, a 0.7% difference. The AMD FirePro M2000 scores 1168, a 1.4% difference. These GPUs would deliver similar frame rates in Roblox, meaning users with any of these alternatives should expect the same performance characteristics: playable at 1080p and 1440p, but not at 4K.

The Verdict

This PC can run Roblox at 2560x1440 and 1920x1080 with all settings presets clearing the 60 FPS threshold. At 2560x1440, the best playable setting is Ultra, which averages 67 FPS. At 1920x1080, the best playable setting is also Ultra, averaging 101 FPS. The system cannot run Roblox at 3840x2160, as no preset reaches 60 FPS. The closest result is Low settings at 58 FPS average, which is below the playable threshold.

For users with a 1080p monitor, this combination provides an excellent experience. Ultra settings at 101 FPS average is smooth and visually appealing. For 1440p users, Ultra settings at 67 FPS is still playable, though the 60 FPS floor is closer. For 4K users, the system will need to run at lower resolutions or accept sub-60 FPS performance. The data suggests that the Intel Arc B370 is the limiting factor, and users seeking 4K performance would need a significantly more powerful GPU. The Intel Core i5-11400F, on the other hand, has enough headroom to support higher frame rates if paired with a stronger graphics card.
